Once again...you can't tell how good the characters are. At a glance, no they wont play as well in the same way, that doesn't mean they wont develop other strengths. The mechanics have changes and that can drastically make characters different. Corner pressure is harder with advancing guard push, but there's also a lot more movement options than we normally see. Sentinal looks slow, but he may be able to play a good keep away or aerial lock out with his normals and may do significant chip like before that he can get with pressure assists.
The games just too different. Until Evo I'm not making any calls, even if they look like ass when I try them. Someone always takes seemingly bad characters and finds a niche.
